Customize:

• PCB width and length

• Maximum component height

• PCB mounting-hole spacing

• Mounting-hole diameter

• Sensor opening diameter

• Cable opening width and height

• Concealed keyholes, external tabs or no wall mounting

The generator automatically creates the enclosure depth, PCB standoffs, screw bosses, ventilation slots and lid fit. The base and four-screw cover are designed to print separately without supports.

PLA is suitable for prototypes and indoor projects. PETG provides better toughness and temperature resistance.

This enclosure is not waterproof and is not certified for mains-voltage applications. Verify dimensions, ventilation and electrical safety before use.
